Tooth avulsion accounts for 0.5% to 16% of dentoalveolar traumas, and prognosis depends on immediate management. The International Association of Dental Traumatology developed an educational poster to guide laypeople in responding to such injuries. This study evaluated children's perceptions of the "Save a Tooth" poster and the knowledge acquired from it. Children aged 8 to 10 years were recruited. The poster's illustrations, children's comprehension, and readability were assessed using instrument 1, while knowledge acquired about emergency management of avulsion was assessed using instrument 2. Both instruments were administered after the poster presentation. Responses to instrument 1 were analyzed by categories, and responses to instrument 2 were classified as correct or incorrect. A total of 58 children from third to fifth grade participated. Most children reported that the poster was easy to understand, used accessible language, presented a new topic, required only one reading, had an adequate length, and would be understandable to peers of the same age. However, participants did not identify with the characters depicted, and fourth-grade students suggested that the poster could include more illustrations. The reported frequency of dental trauma among acquaintances ranged from 36.8% to 65%. All participants expressed interest in reading similar materials. Regarding knowledge acquisition, 65% of third graders, 63.16% of fourth graders, and 66.67% of fifth graders answered the sequence of emergency procedures incorrectly. Although the "Save a Tooth" poster was perceived as engaging and accessible, children demonstrated limited identification with the characters and a low level of knowledge retention regarding the correct sequence of emergency management for tooth avulsion.
Obesity is a key risk factor underlying both obstructive sleep apnea (OSA) and cardiovascular disease (CVD). The objective of this study was to determine differential strength of associations of adiposity indices with recurrent CVD events in patients with established CVD and OSA. Post hoc analyses of the international Sleep Apnea Cardiovascular Endpoints (SAVE) trial where participants with moderate-to-severe OSA and established CVD were randomized to usual care plus continuous positive airway pressure (CPAP) treatment or usual care alone. Cox proportional hazards models were used to evaluate associations of body-mass index (BMI) and waist-to-height ratio (WHtR), with the risk of composite CVD events. Of 2,662 participants with OSA with established CVD, 846 (31.8%) were obese by BMI (≥30 kg/m2), while 2,544 (95.6%) had central adiposity (WHtR ≥0.50). Over a 3.7-year follow-up, conventional BMI categories were not clearly associated with composite CVD events, although spline analyses suggested potential nonlinear associations. In contrast, WHtR showed a clear overall association with composite CVD events (p for overall = 0.0187). In quartile analyses, participants in the highest WHtR quartile had a 1.52-fold higher risk of composite CVD events than those in the lowest quartile (hazard ratio 1.52, 95% CI 1.12-2.05). There was no heterogeneity in the effect of CPAP treatment on composite CVD events or CPAP adherence by any baseline adiposity measures. In this large trial of adults with co-occurring OSA and CVD, nearly all had central adiposity (as assessed by WHtR), which showed a more consistent association with the risk of future CVD events. In contrast, the relationship between BMI and CVD outcomes appeared more complex, suggesting that conventional BMI categories may not adequately capture cardiovascular risk in this population. The SAVE trial is registered at ClinicalTrials.gov (Unique identifier: NCT00738179).
Bystander cardiopulmonary resuscitation (CPR) and early use of automated external defibrillators (AEDs) are key measures to improve neurologically intact survival after out-of-hospital cardiac arrest (OHCA). In Germany, however, heterogeneous emergency medical service structures, insufficient legal frameworks for public-access defibrillation, and only partially implemented CPR training in schools limit the full realization of this potential. This review summarizes the available evidence on school-based CPR training, national and international programs (including "Kids Save Lives"), and innovative mobile AED strategies. As an example, a regional project in the city and district of Osnabrück is presented, in which a non-profit organization has been implementing CPR training in schools since 2020, training both teachers and students. Building on this, regional initiatives have been launched to systematically record and improve the availability of AED locations. Based on these findings, key fields of action for policymakers, emergency medical service providers, and civil society stakeholders are identified. Nationwide, legally mandated CPR training in schools, a structured public-access defibrillation concept including AED registries, and the consistent involvement of local non-profit organizations appear crucial to strengthening the early links in the chain of survival and to sustainably improving outcomes after OHCA. Laienreanimation und der frühzeitige Einsatz automatisierter externer Defibrillatoren (AED) sind zentrale Maßnahmen zur Verbesserung des neurologisch intakten Überlebens nach außerklinischem Herz-Kreislauf-Stillstand (OHCA). In Deutschland verhindern jedoch heterogene rettungsdienstliche Strukturen, unzureichende gesetzliche Rahmenbedingungen für Public-Access-Defibrillation (PAD) und ein bislang nur teilweise implementierter Reanimationsunterricht an Schulen eine optimale Ausschöpfung dieses Potenzials. Diese Übersichtsarbeit bündelt die verfügbare Evidenz zu schulbasiertem Reanimationstraining, zu nationalen und internationalen Programmen (u. a. „Kids Save Lives“) sowie zu innovativen mobilen AED-Strategien. Exemplarisch wird ein regionales Projekt in Stadt und Landkreis Osnabrück vorgestellt, in dem eine gemeinnützige Organisation seit dem Jahr 2020 Reanimationsunterricht an Schulen implementiert und Lehrkräfte sowie Schüler schult. Darauf aufbauend wurden regionale Initiativen zur systematischen Erfassung und verbesserten Verfügbarkeit von AED-Standorten angestoßen. Aus den dargestellten Befunden werden Handlungsfelder für Politik, Rettungsdienstträger und zivilgesellschaftliche Akteure abgeleitet. Flächendeckender, gesetzlich verankerter Reanimationsunterricht, ein strukturiertes PAD-Konzept einschließlich AED-Register sowie die konsequente Einbindung lokaler Non-Profit-Organisationen erscheinen entscheidend, um die ersten Glieder der Rettungskette zu stärken und das Outcome nach OHCA nachhaltig zu verbessern.
The subcutaneous implantable cardioverter-defibrillator (S-ICD) avoids transvenous leads and is a promising option for sudden cardiac death (SCD) prevention in pediatric patients. However, mid-term outcomes and post-shock management strategies remain insufficiently characterized. This multicenter, retrospective observational study included pediatric patients (≤ 18 years) who underwent S-ICD implantation between February 2016 and July 2021. Clinical characteristics, pre-implant screening, procedural details, device-related events, and follow-up data were analyzed. The incidence and management of appropriate and inappropriate therapies and subsequent recurrence were evaluated. Ninety-six patients (median age 14.5 years) were enrolled and followed for a median of 70 months (29-75.0 months). Sensing vector suitability remained stable despite somatic growth. Appropriate shocks occurred in 32 patients (33.7%), while inappropriate shocks occurred in 27 (28.4%). After appropriate therapy, intensified pharmacological treatment and catheter ablation prevented recurrent device therapy in 45.5% and 50.0% of cases, respectively, although device shock occurred in 50.9% despite intervention. Following inappropriate therapy, device reprogramming and lifestyle guidance prevented recurrence in 71.4% of patients (15/21). Device-related infection was rare (2 cases), and no lead fractures were observed. S-ICD therapy demonstrated favorable mid-term safety and efficacy in pediatric patients, with durable sensing performance and a low incidence of device-related infection. Although inappropriate shocks were not uncommon, appropriate post-shock management effectively reduced recurrence, supporting S-ICD as a viable option for selected pediatric patients without pacing requirements.
This study aimed to investigate the effects of short naps on perceived sleepiness and cognitive vigilance during extreme sleep deprivation in ultra-endurance racing. It tested whether baseline cognitive performance predicts nap decisions and if 20-min naps enhance objective cognitive function while reducing subjective sleepiness. An observational field study was conducted during the 2022, 2023, and 2024 editions of the Ultra-Trail du Mont-Blanc® (170 km; ∼10 000 m elevation gain). Sleep was recorded via wrist accelerometery for 52 completing runners (43.9 ± 8.3 years). Subjective sleepiness (Karolinska Sleepiness Scale, KSS) and reaction time (Psychomotor Vigilance Test, PVT) were assessed at five checkpoints (CP0-CP4). At CP1-CP3, participants chose between a 20-min sleep opportunity (nap group, NG) or remaining awake (awake group, AG). Measurements occurred at checkpoint entry (ENT) and 1 km post-checkpoint. Finishers slept an average of 28.4 ± 21.9 min. Linear mixed-effects models confirmed robust circadian modulation of both sleepiness and reaction times. Nap decisions were primarily driven by subjective sleepiness rather than objective vigilance deficits. While 20-min naps produced immediate reductions in KSS 1 km post-checkpoint, cognitive benefits (PVT) manifested more gradually, with significantly faster reaction times observed only at subsequent checkpoints. Brief naps serve as an effective reactive strategy to reduce perceived drowsiness and provide partial protection against late-race performance decline without compromising overall race completion times.

To break down "forever chemicals", bacteria and fungi need a way to avoid or evade their own toxic by-products.
Both type II (consumer/client-on-worker) and type III (worker-on-worker) workplace violence and mistreatment exist within the sign language interpreting field, however type III (also known as horizontal violence or lateral aggression) is more commonly reported. Between 22 to 90% of sign language interpreters have witnessed and/or experienced forms of horizontal violence or behaviors associated with it and 0 to 8% have knowingly perpetrated horizontal violence against another interpreter. This perspective article aims to provide a cross-industry approach by sharing general practices and previous strategies used within the mental and general healthcare settings. We describe how these tools have been adapted to other industries and model how to apply them to the sign language interpreting field. Available regulatory guidance emphasizes employer responsibility for identifying workplace violence hazards and implementing evidence-informed prevention strategies. Safety and Violence Education (SAVE) was designed for front-line healthcare professionals who are exposed to multiple, well-documented risk factors for workplace violence. The original SAVE curriculum primarily emphasized the perceived predominance of consumer/client-on-worker violence in community mental health settings. Critical steps in adapting SAVE for sign language interpreters involved organizational/administrative exposure control strategies, like cultivating awareness of how organizational culture intersects with emotional and psychological safety and emphasized behavioral/interpersonal approaches by recognizing, preventing, and mitigating worker-on-worker aggression, bullying, and relational-based conflict. The adapted SAVE sought to "break the cycle" of horizontal violence and establish a sustainable culture of safety, respect, and professional resilience among sign language interpreters.
Veno-arterial extracorporeal membrane oxygenation (VA ECMO) provides temporary mechanical circulatory support, primarily for patients with compromised cardiac function. In individuals supported on femoral VA ECMO with concurrent pulmonary dysfunction, poorly oxygenated blood may be ejected from the left ventricle resulting in differential hypoxia to the upper body, or Harlequin syndrome. A retrospective, observational review of our institutional experience in managing patients who developed Harlequin syndrome from March 2016 to May 2021 was conducted. We evaluated interventions to correct Harlequin syndrome, pre-cannulation laboratory values, clinical outcomes, and overall survival to discharged. Forty-four patients developed Harlequin syndrome during the study period. Eleven (25%) patients underwent ECMO revision, while 33 (75%) patients did not. The ECMO revision group had a Survival after Veno-Arterial ECMO (SAVE) score of -15 (interquartile range (IQR) -17, -11), while the non-revision group had a SAVE score of -6.0 (IQR -10, -1). The median time to resolution of Harlequin syndrome for the entire cohort was 4.5 h (IQR 1.4, 7.80). Hospital length of stay was similar between groups. There were eight (73%) patients in the ECMO revision group who survived to decannulation, compared to 23 (70%) patients in the non-revision group. Our findings underscore Harlequin syndrome as a serious complication of femoral VA ECMO. Our observed findings also suggest that physiological interventions can effectively resolve Harlequin syndrome and should be considered as a key strategy before considering ECMO revision.

The 3 Abrahamic religions, namely Judaism, Christianity, and Islam, regard the human being as the most noble and perfect being due to their monotheistic attitude and value him above all creatures. This dignity is such that even the human embryo is viewed as a complete and perfect human being. All 3 religions place a high value on unborn life generally and prohibit abortion but allow exceptions when the mother's life is in danger. In Judaism, abortion is permitted to save the mother's life based on the concept of rodef, and some scholars allow it for pregnancies resulting from adultery or potential birth defects. Catholicism uses the principle of "double effect" to justify abortion when necessary to save the mother. Islam prioritizes warding off harm over gaining benefits, permitting abortion only when a certain benefit to the mother outweighs the harm to the fetus. Although there is a controversy over the human embryo in the early days of its formation, all 3 religions agree on the illegitimacy of abortion in the final months of pregnancy. Perhaps the permission of abortion in the event of a risk for the mother's health to preserve her health and well-being is the most important common ground of these 3 heavenly religions. The abortion permission in other cases, such as disability, maiming, is a matter of dispute between the 3 religions.
To develop, clinically implement, and use automated treatment planning for lung cancer radiotherapy (RT) via an in-house treatment planning optimization system, the expedited constrained hierarchical optimization (ECHO). The ECHO system accepts segmented tumor and normal tissue contours and clinical dose/volume criteria as inputs and generates optimized fluence maps for intensity-modulated RT (IMRT) and leaf trajectories for volumetric-modulated arc therapy (VMAT). Dose/volume criteria for our clinically used seven lung cancer fractionation schedules were implemented in ECHO. For each schedule, ECHO internal optimization parameters were tuned using 5-7 previously treated patients and validated with additional 20-25 patients. Since May 2021, a total of 431 lung cancer patients have been treated with ECHO IMRT. Additionally, from April 2023, 93 lung SBRT patients were planned with ECHO VMAT. Treatment plans optimized with ECHO IMRT and VMAT provide more consistent target coverage and similar organ sparing compared with manually optimized plans. The average planning target volume was 390 cm3 (range: 12-3441) for IMRT and 17 cm3 (range: 2.5-56) for VMAT. The average optimization time was 33 min (range: 7-126) for IMRT and 56 min (range: 21-178) for VMAT. On average, ECHO-optimized plans save 1.5 h per plan compared to manual planning. We have implemented an automated system for lung RT treatment planning at our institution for seven fractionation schedules. Our ECHO approach is robust and adapts to changes in clinical criteria without requiring algorithm modifications or retraining. The proposed treatment planning automation framework saves resources and improves treatment plan quality and consistency.
Background/Objectives: The treatment of multidrug-resistant and hypervirulent Klebsiella pneumoniae is one of today's biggest healthcare challenges. The depletion of therapeutic options necessities the application of new methods. One promising approach is to use phage-derived enzymes that target the capsule and make the causative more visible to the immune system. As proteins, these enzymes must be optimised by reducing their size and antigenicity to make them suitable for repeated use. Methods: In this study, the recently isolated and cloned K2B1orf61 K2 capsule-specific depolymerase was analysed structurally, and certain amino acid residues were deleted by cloning. The following amino acid residues were removed from the 80th (D2_N80), 115th (D3_N115), and 200th (D4_N200) N-terminal, and 250 (D5_C250) and 20 (D6_C20) from the C-terminal positions of the wild-type molecule (D1_wt). The resulting derivative molecules were compared with in vitro and in vivo tests. Results: In the presence of wild-type depolymerase, human serum was able to eliminate the target bacterium and save the lives of mice challenged with the bacterium in an originally lethal intraperitoneal model. However, the D5_C250 derivative lost all activity, meaning that the bacteria with the K2 capsule in the serum survived and all the mice died. Derivatives D2_N80, D3_N115, and D6_C20 exhibited prolonged activity in the serum killing assay, effectively eliminating bacteria within 5 h. Similar activity differences were revealed in the intraperitoneal experiment: D5_C250 had no rescue effect; however, D1_wt, D2_N80, D3_N115, D4_200, and D6_20 resulted in survival rates of 100%, 60%, 80%, 100%, and 20%, respectively. Conclusions: Our results demonstrate that molecular trimming is a promising procedure for developing ideal therapeutic depolymerases.
Virtual critical care (VCC) programs provide remote specialist support to community hospitals caring for critically ill patients, yet Canadian evidence regarding their economic impact remains limited. This study aimed to estimate the cost savings associated with a newly implemented VCC program in Eastern Ontario. A retrospective cost-benefit analysis of the first 19 months of a regional VCC program based at a tertiary academic center supporting 13 community hospitals was conducted. All adult patients with an initiated VCC consultation were included. Cost estimates focused on avoided interfacility transfers, transportation costs, and differences in inpatient costs between academic and community hospital settings. Descriptive statistics were used to compare estimated cost savings with program operating costs. Between April 2023 and October 2024, 473 VCC calls representing 312 unique patient encounters were recorded (298 patients included in analysis). Transfers to larger centers were avoided in 179 cases (60%). Avoided land ambulance transfers were estimated to save $61,101 CAD over the study period. Estimated inpatient cost savings associated with avoided transfers ranged from $687,643 CAD (mean length of stay [LOS]) to $2,681,420 CAD (median LOS), corresponding to monthly savings of $36,191-$141,127 CAD. These savings approached or exceeded the estimated VCC program monthly operating cost. The Eastern Ontario VCC program was associated with substantial estimated cost savings, primarily through avoided transfers and reduced use of high-cost academic intensive care beds. These findings support VCC as a potentially cost-effective health system intervention for supporting critically ill patients in community hospitals.
Addressing stigma, mental health, and health care access challenges for people living with HIV requires a multifaceted approach. Generative artificial intelligence (GenAI) chatbots may be one component of this approach. GenAI chatbots can reduce travel costs and save time. They provide opportunities to offer users a discreet alternative to human interaction, helping reduce stigma and improve comfort. They are easy to use, have multilingual capabilities and high levels of user satisfaction. Emerging evidence on GenAI chatbots suggests promising potential for enhancing HIV prevention, such as supporting HIV self-testing and providing information on PrEP, counseling, providing access to information, and role-playing HIV status disclosure. Successful implementation of GenAI for HIV care, however, requires careful consideration of ethical and practical issues to ensure safe and responsible use. Building user AI knowledge, trust, and ensuring ethical integrity will require meaningful collaboration between technologists, clinicians, researchers, and those most affected by HIV.
Peripheral arterial disease (PAD) is one of the most common underlying causes of major lower extremity amputations (LEAs). Often revascularization is not adequate to save the leg. Tibial Transverse Transport (TTT) represents a revolutionary approach to increase angiogenesis in people with critical limb threatening ischemia (CLTI). A systematic review and meta-analysis was conducted across six databases. Inclusion criteria required studies to evaluate TTT combined with revascularization versus revascularization or TTT alone as a monotherapy. Outcomes analyzed included tarsal-metatarsal amputation (TMA), wound healing, and change in visual analogue scale (VAS) for pain. A total of five studies were identified across four databases that met inclusion criteria. TTT + Revascularization was shown to have a protective effect in reducing follow up TMA, O.R = 0.44 [0.23, 0.81], p = 0.009. TTT + Revascularization was also found to have an association with wound healing, OR = 3.25 [1.84,5.73], p = 0.0001. Four studies observed the change in Visual Analogue Scale (VAS), and the cumulative effect showed no association between either TTT + Revascularization or monotherapy with change in VAS pain pre and post procedure, standard mean difference = -0.05 [-0.16, 0.05], p = 0.33. TTT in combination with peripheral endovascular revascularization offers a promising addition for patients with CLTI with lower incidence of TMA increase rates of wound healing. However, considering the limited studies available and overall small sample size, further trials are necessary to understand the relationship between this novel therapy and CLTI management.
We encountered a male infant with extremely low birth weight born at 22 weeks and 0 days of gestational age in the toilet at home. He was resuscitated with chest compression and bag-valve-mask ventilation by the emergency medical service crew and was transported to our institution 50 minutes after birth. The patient was intubated and given intratracheal artificial surfactant after admission. After he recovered from the initial hypotensive phase, we maintained the blood pressure at an appropriate level using nitroglycerin to avoid cerebral overcirculation. He was discharged home at 170 days of life with no signs of intraventricular hemorrhage or periventricular leukomalacia. His overall developmental quotient at one year and seven months of corrected age was 104, and he showed no apparent developmental delay. This case demonstrates that appropriate medical management can save the lives of extremely preterm infants born outside medical institutions.
To compare the reimbursements associated with posterior blepharoptosis, ectropion, entropion, pterygium, and chelation for band keratopathy surgeries performed in an operating room versus an office procedure room and assess the potential benefit of incentivizing the use of the more cost-effective option. Economic analysis. The 2022 Centers for Medicare and Medicaid Services database was used to determine the reimbursement for each procedure when performed in the operating room and office procedure room. Total services for each procedure were aggregated and used to estimate the total cost to the healthcare system based on location.Overhead costs for office procedures were calculated by examining the 3 main costs associated with these office procedures: disposables, human resources, and physical facilities.An incentive analysis was performed, which involved calculations examining the change in annual cost to Medicare if the reimbursement for the study procedures were increased to include overhead costs and various incentive payment percentages. Procedures performed in the operating room cost an average of $2200 more than office procedures. The average overhead cost for office procedures was $150. The total cost of the study procedures in 2022 was $177 million, with >90% of procedures performed in the operating room. Increasing reimbursement by 150% the cost of overhead, when 50% of procedures are performed in the office, saves the healthcare system $52 million. Increasing office reimbursement to cover overhead costs and provide a small incentive to perform procedures in the office could save the healthcare system millions of dollars.
This article examines the impact of artificial intelligence (AI) on cognitive processes and clinical practice, highlighting a delicate balance between benefits and risks. While AI enhances productivity and access to information, it also promotes cognitive offloading and deskilling, the progressive loss of clinical, decision-making, and interpersonal skills, exacerbated by automation bias and reliance. Several studies indicate reduced cognitive activity and autonomous performance when AI is heavily used, despite its proven effectiveness in diagnostic support. They are necessary mitigation strategies to preserve critical thinking and models of human-AI integration to save human clinical judgment. AI should not replace clinicians but support them, keeping core competencies such as critical thinking, empathy, and responsibility at the center.
